Welcome to the Hemoglobin module!

Visible on the display are four copies of the protein hemoglobin.

The protein hemoglobin is responsible for getting the oxygen you breathe from your lungs to all the cells in your body. Within the core of each hemoglobin protein is a heme molecule, which binds one oxygen molecule to its central iron atom. Hemoglobin commonly forms a so-called "tetramer" in which four copies of the protein come together for more efficient oxygen transport around the body. The heme is held in place through a coordination bond with the nitrogen of a key histidine amino acid, His92, shown in the model as sticks bound to the heme. Despite its size, each hemoglobin tetramer only carries up to four oxygen molecules at a time.
